WitrynaThe method of functional derivatives is applied to investigate the Anderson model. It is shown that the presence of magnetic field and the direct interaction between impurities lead to the same form of the low-temperature resistivity per impurity in arbitrary order of the perturbation series in the symmetric case of the Anderson model. The formal … Witryna10 sie 2012 · The paper is organized as follows: In Section II we present the periodic Anderson model written in terms of Hubbard operators.
